+# Distributed Locking
+Distributed locking is technique to manage many applications that trying to access the same resource.
+The main purpose is to allow only one of many applications to access the same resource at the same time.
+Otherwise accessing the same object from various applications may corrupt the value of resources. 
+
+> ABP's current distributed locking implementation is based on the [DistributedLock](https://github.com/madelson/DistributedLock) library.
+
+## Installation
+
+You can open a command-line terminal and type the following command to install the [Volo.Abp.DistributedLocking](https://www.nuget.org/packages/Volo.Abp.DistributedLocking) package it into your project:
+
+````bash
+abp add-package Volo.Abp.DistributedLocking
+````
+
+This package provides the necessary API to use the distributed locking system, however, you should configure a provider before using it.
+
+### Configuring a provider
+
+The [DistributedLock](https://github.com/madelson/DistributedLock) library provides [various of implementations](https://github.com/madelson/DistributedLock#implementations) for the locking, like [Redis](https://github.com/madelson/DistributedLock/blob/master/docs/DistributedLock.Redis.md) and [ZooKeeper](https://github.com/madelson/DistributedLock/blob/master/docs/DistributedLock.ZooKeeper.md).
+
+For example, if you want to use the [Redis provider](https://github.com/madelson/DistributedLock/blob/master/docs/DistributedLock.Redis.md), you should add [DistributedLock.Redis](https://www.nuget.org/packages/DistributedLock.Redis) NuGet package to your project, then add the following code into the `ConfigureServices` method of your ABP [module](Module-Development-Basics.md) class:
+
+````csharp
+using Medallion.Threading;
+using Medallion.Threading.Redis;
+
+namespace AbpDemo
+{
+	public class MyModule : AbpModule
+	{
+		public override void ConfigureServices(ServiceConfigurationContext context)
+		{
+			var configuration = context.Services.GetConfiguration();
+			
+			context.Services.AddSingleton<IDistributedLockProvider>(sp =>
+			{
+				var connection = ConnectionMultiplexer
+                    .Connect(configuration["Redis:Configuration"]);
+				return new 
+                    RedisDistributedSynchronizationProvider(connection.GetDatabase());
+			});
+		}
+	}
+}
+````
+
+This code gets the Redis connection string from the [configuration](Configuration.md), so you can add the following lines to your `appsettings.json` file:
+
+````json
+"Redis": {
+    "Configuration": "127.0.0.1"
+}
+````
+
+## Usage
+
+There are two ways to use the distributed locking API: ABP's `IAbpDistributedLock` abstraction and [DistributedLock](https://github.com/madelson/DistributedLock) library's API.
+
+### Using the IAbpDistributedLock service
+
+`IAbpDistributedLock` is a simple service provided by the ABP framework for simple usage of distributed locking.
+
+**Example: Using `IAbpDistributedLock.TryAcquireAsync` method**
+
+````csharp
+using Volo.Abp.DistributedLocking; 
+
+namespace AbpDemo
+{
+    public class MyService : ITransientDependency
+    {
+        private readonly IAbpDistributedLock _distributedLock;
+		public MyService(IAbpDistributedLock distributedLock)
+        {
+            _distributedLock = distributedLock;
+        }
+        
+        public async Task MyMethodAsync()
+        {
+            await using (var handle = 
+                         await _distributedLock.TryAcquireAsync("MyLockName"))
+            {
+                if (handle != null)
+                {
+                    // your code that access the shared resource
+                }
+            }   
+        }
+    }
+}
+````
+
+`TryAcquireAsync` may not acquire the lock. It returns `null` if the lock could not be acquired. In this case, you shouldn't access the resource. If the handle is not `null`, it means that you've obtained the lock and can safely access the resource.
+
+`TryAcquireAsync` method gets the following parameters:
+
+* `name` (`string`, required): Unique name of your lock. Different named locks are used to access different resources.
+* `timeout` (`TimeSpan`): A timeout value to wait to obtain the lock. Default value is `TimeSpan.Zero`, which means it doesn't wait if the lock is already owned by another application.
+* `cancellationToken`: A cancellation token that can be triggered later to cancel the operation.
+
+### Using DistributedLock library's API
+
+ABP's `IAbpDistributedLock` service is very limited and mainly designed to be internally used by the ABP Framework. For your own applications, you can use DistributedLock library's own API. See its [own documentation](https://github.com/madelson/DistributedLock) for details.
